Chameleons (Chamaeleonidae) are arboreal lizards that use their color-changing skin and rapid, sticky tongues to hunt insects. Although most chameleon species are native to Madagascar and Africa, some are also found in Asia and Europe. Chameleons can adapt to habitats ranging from rainforests to deserts. There are over 200 species of chameleons, which exhibit a wide range of sizes, from tiny, thumbnail-sized species to large lizards comparable in size to a housecat. However, the veiled chameleon (Chamaeleo calyptratus) and the panther chameleon (Furcifer pardalis) are among the most widely available species kept as pets. Continue reading to discover how big veiled chameleons and panther chameleons get.
How Big Do Veiled Chameleons Get?
Veiled chameleons are hardy arboreal lizards that are native to Yemen and Saudi Arabia. Mature males of the species are between 18 and 24 inches long and weigh from 3.5 to 11 ounces. Mature females are notably smaller, at 10 to 14 inches long and typically weigh under five ounces, unless they are carrying eggs.

Due to its popularity in the pet trade, the veiled chameleon is bred in captivity and has established populations in Florida.

Veiled chameleons make fascinating display pets due to their vivid colors, unique casque (head crest), and hunting behaviors. Veiled chameleons are not companion animals; they do not enjoy being handled and find it highly stressful.
Veiled chameleons are solitary, territorial creatures that require a large, vertical, well-ventilated mesh enclosure filled with branches and live plants for climbing and hydration.
A chameleon enclosure cannot be too big, as larger spaces offer more room for climbing. The enclosure should be filled with branches and foliage to prevent the chameleon from feeling exposed or stressed.

Veiled chameleons typically weigh less than one pound.
Veiled chameleons are widely considered the easiest beginner chameleons due to their hardiness, adaptability, and availability. Despite their hardiness, veiled chameleons are still fragile and high-maintenance pets.
How Big Do Panther Chameleons Get?
Due to their vibrant, rainbow-like colors and more docile nature, the panther chameleon is rapidly overtaking the veiled chameleon as the most popular pet chameleon. Although veiled chameleons are mainstays in pet stores, panther chameleons have become the preferred captive-bred choice for experienced reptile enthusiasts.

Native to the forests of Northern and Eastern Madagascar, panther chameleons are slightly smaller than veiled chameleons. Mature males (12–20+ inches, 5-7 ounces) are significantly larger than mature females, which are between 7 and 14 inches long and weigh 2 to 3 ounces. This noticeable size difference is attributed to sexual dimorphism, a condition in which males and females of the same species exhibit different physical characteristics.

Panther chameleons are poised to become the most popular chameleon pets.
Like the veiled chameleon, panther chameleons are not ideal pets for beginners. They are fragile, solitary, high-maintenance pets that require large, climate-controlled enclosures.
In addition to being high-maintenance, veiled chameleons and panther chameleons also require a significant initial financial investment, which can amount to several hundred dollars or more depending on setup and equipment.
